Ancient Egypt is typically divided into three major historical periods: the Old Kingdom (c. 2686–2181 BCE), which lasted about 500 years; the Middle Kingdom (c. 2055–1650 BCE), lasting approximately 400 years; and the New Kingdom (c. 1550–1070 BCE), which spanned around 480 years. Each period was marked by distinct developments in culture, governance, and architecture, reflecting the evolution of ancient Egyptian civilization over time.

The measurement of Earth's history divided into time periods is called the geological time scale. It is divided into eons, eras, periods, epochs, and ages, with each unit representing a significant change in Earth's geological and biological history.
The four long periods of history are ancient history, medieval history, modern history, and contemporary history. These periods are typically divided based on major social, political, and cultural developments that occurred during each time period.
geologic time scale
The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.

Geologic history is divided into four main eons: Hadean, Archean, Proterozoic, and Phanerozoic. These eons are further divided into eras, periods, and epochs based on significant events and changes in Earth's geology and life forms. Each division represents a distinct time period characterized by specific geologic or biological features.
